自旋霍尔效应理论述评

Comment on Theory of spin Hall effect

J. E. Hirsch

摘要:

Chudnovsky最近提出(arXiv:0709.0725)一个漂亮的简单机制的内在自旋霍尔效应涉及的德鲁德模型的扩展。我们指出,我们在Phys.Rev.B60,14787(1999)(arXiv:cond-mat/9910408)中对该问题的另一种处理方法中提出了一个等效的建议,得出了相同的结论。这两种方法的一致性支持了它们的物理有效性。该机制适用于所有金属和半导体中的自旋霍尔效应以及所有铁磁金属和半导体中的反常霍尔效应。

英文摘要:

Chudnovsky recently proposed (arXiv: 0709.0725) a beautifully simple mechanism for the intrinsic spin Hall effect involving an extension of the Drude model. We point out that an equivalent proposal was made by us in an alternative treatment of the problem in Phys.Rev. B60, 14787 (1999) (arXiv:cond-mat/9910408, reaching identical conclusions. The coincidence of both approaches supports their physical validity. The mechanism applies to the spin Hall effect in all metals and semiconductors and to the anomalous Hall effect in all ferromagnetic metals and semiconductors.
